I am installing a compressor etc on the truck and wanted to use a battery isolator from a dual battery setup so that the compressor cant run untill the alternator is charging .
Got it all wired but ran into an issue I didnt think of. The battery islolator expects to see voltage on both sides of the switch.
Now my idea is to install a small 12v bike battery in the back so it will charge that etc and see the voltage. I will run my strobe lights or something from that.
Anyone see any other way I can get 12v on the second side of the switch and still have it working as an isolator so the compressor wont run until the engine is running
